Problem importing NLTK packages

  

    

      

from nltk.machado import *

    

  

Traceback (most recent call last):
File "<pyshell#8>", line 1, in <module>
from nltk.machado import *
ModuleNotFoundError: No module named 'nltk.machado'

However, when I run the same command for the book package, Python imports

  

    

      

import nltk

             

from nltk.book import *

    

  

What would be the solution? Hugs
